It isfurther proposed in the present invention to arrange my improvements in such a manner that the entire bar may be stamped out of one piece, and the means for drawing lines may be obtained by mere bending of portions of said blank.

Further objects and advantages of the present invention will appear as the specification proceeds.

The preferred form of my invention is illustrated in the accompanying drawing in which Figure 1 shows a side view of my tool in contracted condition; y Y

Figure 2 is a similar side view of the tool in expanded position;

Referring to the drawing inwdetail it willabe *seen particularly from Figure 2 that a plurality of links 1 are pivotally connected at theircenters as at 2, and at their upper and lower ends 3818.53 and 4 soas to forma setorg lazytongs. A plurality of bars 5 are pivotally connectedto the pivots 3 in any suitable manner, andjare formed with slots 6 in which-.the;;pivots :4;are;made to ride, the latter pivots rbeingpreferably ,formed with heads 7 which-hold the pivo'ts in; the; slots. In this manner the bars araarranged in parallel relation, and are, evenly spaced? from:.mie ianother, and thespacing between the barst maybe uniformly adjusted bygcontractiongorj'eirpansion of the lazytongs. vThe two .end ba'rs marked 51 and 5?

;-z,,,The transverse bar 9 is provided with a number of teeth -1 1 the bottom; face thereof ,--and :these :teeth areiradapted for-"engagement, with a pin-l2 projecting from the second bar -5,'-s o that when any set of teethtengages-with the ipin 1 2;the;lazy tongsare heldin adjustedposition; \Theopposite end member 5 has a slot 13 j-inthe upperfiend thereof; in alignment with the; swingingplane of the transverse bar 9 so that when the entire de- The bars 5 are all of the same length and] project beyond the pivots 4 and are pointed as shown at 14 so that they may be used as puncturing tools in the manner described in-the pre-;

vious application. I a

In the present application the principal novel feature resides in the means for drawing straight lines arranged on the opposite ends of the bars 5. For this purpose the latter bars which are preferably made of a thin sheet of metal as indicated in Figures 4 and 5, are provided witha disc 15 arranged to revolve in a transverse plane,

and with a blade section 16 arranged in the same plane as the disc, the blade section 16 having a cutting edge 17, arranged at a slight angle to the horizontal plane when the bar is in a vertical position; and projecting slightly beyond the disc so that an extension of the cutting edge would just clear the disc as indicated by the dotted line 18. The blade section 16 which is preferably made of the same thickness as the disc 15 is arc-shaped'adjacent the disc as shown at 19, and is provided with a second cutting edge 20 facing away'from the disc so that the second cutting edge may be used without the disc becoming active;

The bar 5 is preferably made out of the blank shown in Figure '5which shows two arms 21 projecting from the bar near one extremity thereof in slightly inclined direction, while the blade section 16 forms the extremity of the bar 5 and is,

The operation of the device may be easily understood from the foregoingdescription. If the device is to be used as a puncturing tool, it is preferably employed in its contracted position as shown in Figure 1 so that a person may take hold of the device with one hand, and puncture the object by successive applications. If the tool is to be usedas a mere marking tool, that is for establishing uniformlyspaced points on an object, the tool may be used in the form shown in Figure 2 with the two end members spaced from one another so as to span "the entire object, and the device lockedin position by the bar 9. Pressing: down'of the points 14 into the, object will define the desired marks. If it is desired to draw a series of parallel lines over'an object or to groove the object, or even cut the same along parallellines, the upper structure of the bars 5 is used.

First the device is again adj'usted'so that the end bars span the entire width thereof, and then the discs 15 are pressed into the object; "then the entire device is drawn over the-same so that the discs draw parallel lines of the desired spacing across the object.- These lines may be in the nature of grooves, if a grooving of the object is desired, or may even out through the object if such is the desired eflect. The blades 16 follow the grooves made by the discs, and they may be used for the purpose of deepening the groove by suitable tilting of the instrument. The blades serve the further purpose of steadying the hand of the operator, since they ride in the grooves made by the discs, and thereby hold the discs to a straight line. If for certain purposes the discs cannot be used to advantage the operator may turn the device around and use the cutting edges 20 of the blade.

I claim:

1. In a tool of the character described, a plurality of marking bars, means for supporting the same in a single plane in evenly spaced relation with freedomof uniformly increasing and decreasing the spacing, sets of ears projecting transversely from the bars near the ends thereof, discs revolvably supported between the ears in transverse relation to the bars and offset from the plane thereof, and guide blades formed integral with the bars and projecting transversely, from the plane of the bars in an opposite direction and in trailing relation to the discs.

2. In a tool of the character'described, a plurality of marking bars, means for'supporting the 25 same in evenly spaced relation with freedom of uniformly increasing and decreasing the spacing,

and guide blades arranged in registering ends of the bars and in transverse relation thereto, the guide blades being formed integral-with the bar and being twisted in transverse direction.

3. A blank for a marking bar of the character described comprising a flat bar having arms extending therefrom in opposite directions near one extremity thereof, and having a blade section at said extremity and a neck portion connecting the blade section and the bar so as to allow the blade to be turned at right angles to the bar by twisting the'neck'portion and to allow the arms to be bent at rightangles relative to the bar so as to form a bearing for a disc to be alined with the blade section;

4. A marking bar of the character described having a blade section at one extremity thereof, A
